CAUTION: Perform the test at normal operating fluid temperature (50 — 80°C or 122 — 176°F). 1. "D" RANGE TEST IN NORM, AND PWR PATTERN RANGES Shift into "D" range and hold the accelerator pedal constant at 50 % and 100 % throttle valve opening positions. Push in one of the pattern selector buttons and check the following: (a) 1-2, 2-3, 3-OD and lock-up up-shifts should take place, and shift points should conform to those shown in the automatic shift diagram. NOTE: (1) There is no 3rd up-shift or lock-up when coolant temperature is below 35°C (95°F) and speed is under 48 km/h (30 mph). (2) There is no OD up-shift or lock-up when coolant is below 63°C (145°F) and speed is under 63 km/h (39 mph), or if there is a 10 km/h (6 mph) difference between the set cruise control speed. EVALUATION (1) If there is no 1 → 2 up-shift: • No.2 solenoid is stuck • 1-2 shift valve is stuck (2) If there is no 2 → 3 up-shift: • No.1 solenoid is stuck • 2-3 shift valve is stuck (3) If there is no 3 → OD up-shift (throttle valve opening 1/2), • 3-OD shift valve is stuck (4) If the shift point is defective: • Throttle valve, 1-2 shift valve, 2-3 shift valve, 3-OD shift valve etc., are defective. (5) If the lock-up is defective: • No.3 solenoid is stuck • Lock-up relay valve is stuck (b) In the same manner, check the shock and the slip at 1 → 2, 2 → 3 and 3 → OD up-shifts. EVALUATION If the shock is excessive: • Line pressure is too high • Accumulator is defective • Check ball is defective
